DESCRIPTION
This laser driver is an electronic module designed for
driving diode lasers with up to 2A constant current, high
efficiency, low noise, high reliability, zero EMI, and small
package. Figure 1 shows physical photo of ATLS2A201D.
It provides these the functions: laser constant current control,
laser current monitoring, over current and thermal protection,
laser current control indication, laser diode status indication,
soft start, and shut down.
It comes with a high stability low noise 2.5V voltage
reference output which can be used for setting the output
current. The reference output can also be used for the ADCs
(Analog to Digital Converters) and/or DACs (Digital to
Analog Converters).
